For the past few months (probably a year now), the forgotten music channel NickMusic has started playing 2023 We Make Fun bumpers despite the channel not having the splat rebrand. The channel has also used one of the 2023 fonts Nickelodeon uses on the top right corner for "TYLA'S KCA TAKEOVER". Maybe the channel might rebrand someday? The channel is still in SD so maybe it's taking a while cuz either they forgot about it or they're converting it to HD as I speak....
